I find myself using lesser and lesser add-ons as the years passes (idk why). Right now it's just a matter of:<p>* SearchPreview (I'm so used to that little screenshot on the search results... can't live without it anymore).<p>* FlagFox (Just for the curiosity where the website is hosted!)<p>* Pocket (Mostly links that I found at work but didn't had time to read there, I then read at home)<p>* AdBlock (Yeah, guilty. Download websites becames sane plus I <i>hate</i> so much thosein video ads at youtube ).
Only extension I use with Safari and Chrome is Adblock. When browsing, I don't feel any need for additional features that are not offered by browser and OS.<p>As my ecosystem is Mac/iOS, I use Add to Reading List in Safari to save articles that I may read/refer later. One Feature I really like in Safari is Reader which removes extraneous stuff on a page and makes it easy to share/email/read/print the main content.
I've cut down on the extensions I use over the years. Here's my entire list:<p>* HTTP Switchboard - useful for debugging/blocking annoyances, also doubles as an adblocker<p>* LastPass - honestly, I'd probably be using 1Password if they had a linux client<p>* PDF Viewer - Mozilla endorsed drop-in pdf.js plugin<p>* Smile Always - converts amazon.com uris to smile.amazon.com, which donates a portion of your purchases to charity
LastPass, Personal Blocklist (Google.com), Google Cast (Chromecast), HTTPS Everywhere (EFF), RES, Google Keep (cross-platform PostIt notes), and Google Docs (depreciated).<p>I no longer use an advert removal addon as they seem to make more issues than they solve, plus some sites do legitimately deserve to get paid.<p>I do however turn on Click-To-Play for all browser plugins (Flash, Java, etc) which stops a lot of the worst adverts.
The only one not mentioned so far that I use is DownThemAll.<p><a href="https://addons.mozilla.org/en-US/firefox/addon/downthemall/" rel="nofollow">https://addons.mozilla.org/en-US/firefox/addon/downthemall/</a><p>It's nice for when you want to download a lot of files that appear on a page.
In Chrome:<p>* Checker Plus for Gmail<p>* Google Cast<p>* Hangouts (I use this with a lot of people instead of SMS now, its great to be able to switch back and forth between my phone and Chrome)<p>* Lastpass<p>* Rapportive<p>* Reddit Enhancement Suite<p>* TeX the World<p>* Videostream (for Chromecast, so I can stream MKVs locally)
